> Oddly, current mortality and morbidity statistics tend to show that the persons with longest expected lifespans are not persons with "normal" weight as defined by body mass index but rather persons who are (slightly) "overweight." Does that mean "overweight" is a misnomer? Or are people wrong when they conflate a normal weight with a healthy weight?
